Biography: Toyohiko Yatagai received the BE and DE degrees in applied physics from the University of Tokyo, in 1969 and 1980, respectively. From 1970 to 1983 he was with the Institute of Physical and Chemical Research, Japan, where he worked on optical instrumentation, computer-generated holography and automatic fringe analysis. He moved to University of Tsukuba as a Professor of Applied Physics in 1983. He is now a Director of Center for Optical Research and Education at Utsunomiya University. His current research interests include optical computing, optical measurements, holography, and spectral optical coherence tomography for biological applications. He received Optical Research Award from the Japan Society of Applied Physics in 1978 and Denis Gabor Award from SPIE in 2017. He is a member of Optical Society of Japan, a fellow of OSA, SPIE and Japan Society of Applied Physics. He is 2015 President of SPIE. He is the author of 10 books and more than three hundred academic papers in applied optics.

Abstract: A basic spectral relation between a 3-Dobject and its 2-D diffracted wavefront has been derived by interpreting the diffractioncalculation in the 3-D Fourier domain. Information on the 3-D diffracted object is clearly understood by usingthis relation. After the derivation, a method for obtaining the Fourierspectrum that is required to synthesize a hologram with a realistic samplingnumber for visible light is described. Some fast calculation methods for the diffraction calculation, including the hidden surface removal are discussed.  In order to verify the validity and thepracticality of the above-mentioned spectral relation, fast calculation of aseries of wavefronts radially diffracted from a 3-D voxel-based object isdemonstrated.A full-color reconstruction technique is described. Finally, a method for a continuous optical rotation compensation in a time-division-based three dimensional display with a rotating mirror is presented.
